Hi Binoy,

Cat5 should work fine but if you have gig interfaces with poe and option for 5e is possible it is recommended but if option for 5e is not possible cat5 should work fine with poe gig interfaces also.

Binoy,

Cat5 shouldn't be a problem with POE

Power can be supplied in two ways over CAT cables:

For Cisco ILP, inline power is provided over data pairs 2 and 3 (RJ-45 pins 1,2 and 3,6) at 48V DC.

For IEEE 802.3af, power can be supplied in the same fashion (pins 1,2 and 3,6) or over pairs 1 and 4 (RJ-45 pins 4,5 and 7,8).

HTH, rate if it does
